Because master chief rocks.
No but other Spartans appear. This takes place before the majority of the Spartans were killed.
Yes, If you read the books you can tell. There were hundreds of others. There are also Spartans in Halo: Reach.
Actually there is no "Master Chief" in halo wars but only other Spartans and O.D.S.Ts but if you are referring to Halo3, no Master Chief does not die but goes into hypersleep.Halo Wars takes place 20 years BEFORE the other games. Plus, Halo Wars happened 20 years BEFORE Master Chief and the halo trilogy. Also all the Spartans in Halo wars are the spartan IIs in The halo trilogy was after the spartan III project
Yes, in Halo 4 you play as Master Chief and soon find other Spartans (Commander Palmer is the leader of them)
Yes, Master Chief, aka SPARTAN-117, aka John-117, is a human. Albeit, he is a bio-medically, genetically, and mechanically enhanced human. If you want the complete story behind Master Chief's origins, as well as the other SPARTANs' origins, find a copy of Halo: Fall of Reach. This tells how the SPARTANs came to be.
they survived by being dominant over the other countries
well bungies last involvement in the franchise halo will be reach but they are going to create a halo 4 with Master Chief again because if you wait after the credits Master Chief and Cortana survive but it will be entirely made by Microsoft
Master chief and the other Spartans had just been assigned to travel on the pillar of autumn but before they could leave the covenant attacked reach, the master chief decided to let most of his spartan team to go down to the planets surface while he took the seemingly more dangerous job of fighting in space combat. This is why he remained on the pillar of autumn until the begining of halo 1
The covenant attacked the planet 'Reach' where the Spartan's were created. Master Chief escaped on the Pillar of Autumn and some other Spartan's survived the attack but later contact was lost and are presumed dead.
In Halo Wars, there are a number of Spartan II's still alive. Master Chief was a Spartan II, so he may be helping out, but you cannot play as him. However, you can play as other spartans, like Lucy, a sniper, ect. Each spartan has a signature weapon (in campaign), like a spartan laser, a gun turrent, ect.
No the closest they came to each other was Nobel 6 on the cannon, and master chief on the autumn
They say no Spartans die, they just go MIA (Missing In Action), but in Halo Legends in one of the episodes Master Chief, and a group of Spartans try to breach a Covenant ship, but they are in space, and some Spartans are blast off of the vehicle they are on. On a different episode a female spartan fights a brute saving a ODST's life, but dies in the process. So Spartans die in the same way as other military units, but some die in harder, and more painful than others, slower, and or quicker.
